Good to hear from you Ralph:
There were problems I have been working on and have gotten Xsane to work
now. It came down to installing the package libusb-0.1.so.4 .

# scanimage -L
device `brother3:bus4;dev2' is a Brother MFC-295CN USB scanner
So I have a question now though. When launching Xsane GUI the
application window opens very small and cannot be resized in it's
Konsole window then. I must then move Xsane application and preview
windows to another workspace where then the application menu show up
legibly. Using KDE Plasma with Wayland for the Desktop Environment. Can
this issue be debugged and fixed?
Here is a screenshot of what I am describing :< https://ibb.co/YTcF9DrB
There is also an openSUSE Forums thread which I opened here :<
https://forums.opensuse.org/t/brother-mfc-295cn-network-connected-printer-fails-to-scan/191648/70
This led to the final ability for Xsane able to scan and detect the
MFC-295CN scanner.
Thanks

Hi,
This model was released around 2009 so it is one of the older machines.
You really have two options at this point.
1) install Brother's scanner driver. They do have a Linux driver on
their website that mostly works although they don't update them very
often and some people have trouble on new distributions related to
dependencies or in the case of Ubuntu derivatives, issues with the
placement of libraries.
2) You could try our brother_mfp backend which is currently in
development. For some people, it works good enough. It is USB only at
this stage, but if you are interested I can help you set it up. Some
details here: https://gitlab.com/sane-project/backends/-/

Let me know.
Cheers,
Ralph

I am wondering if I could get some help debugging the following output.
The MFC-295CN has wonderful print but I simply cannot get it to scan.

Is the MFC-295CN simply to old to be able to scan well anymore?
-Thank you for any thoughts on this.
